Trader consensus at near-100% implied probability for a 70-71°F high in Chicago on September 18 reflects verified National Weather Service observations at primary stations, which recorded a daily maximum in that narrow range. Persistent cloud cover, southeasterly flow, and moisture from an approaching system limited daytime heating well below the 1991-2020 normal of roughly 75°F, consistent with model guidance issued in the prior 48 hours. This skin-in-the-game assessment draws on real-time surface data and climatological context showing suppressed diurnal ranges under overcast conditions. A realistic challenge would require substantially clearer skies or an unexpected warm-air advection event, neither of which occurred before the observation window closed.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=kord
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
